TNF Summit L5 GTX Jacket is my Go-To Alpine/Mountaineering companion and work horse. I have used it all over the Cascades and Olympic Mountains in Washington. It's extremely durable, very light and very packable. I LOVE this GTX hard Shell. I feel that this jacket is misrepresented in the Backcountry "recommended use" description. For me, This jacket not a backcountry skiing/snowboarding jacket, but a nonsense Alpine/ Mountaineering shell. The cut on this jacket is exactly the way I love it - regular, and just enough to layer mid levels underneath. The huge chest pockets are the most practical features I've seen of any other jackets. Typically, I use Arc'teryx and Patagonia Alpine/ Mountaineering/Expedition Gortex shells, however from my experience this past year, The North Face Summit Series alpine climbing apparel lineup surpassed most other technical apparel makers . This TNF L5 Summit GTX shell rivals if not exceeds the products of the other two companies I've mentioned, finally bringing the power of "technical innovation" back into their Summit Series product line. Initially, I purchased the "NTF Black/Canary Yellow" jacket. After several trips into the Cascades, WA, I loved it so much that I then followed up and purchase the "Fiery Red" color, as well. After numerous years suffering on the alpine mountaineering apparel front, TNF has bounced back with the some of the best products on the market. I LOVE this jacket, and would recommend it to whomever is a mountaineer or alpinist. KEEP IT UP HORTH FACE!!!
